AB - Abstracts: 2017 San Antonio Breast Cancer Symposium; December 5-9, 2017; San Antonio, TexasBACKGROUNDApproximately 7% of women diagnosed with breast cancer (BC) are under 40 years old. Chemotherapy may adversely affect ovarian function therefore fertility is an issue to be addressed for these patients. Patients with cancer in Latin America have limited access to fertility preservation. However age at first birth in women from Latin America is lower than in developed country and the needs of fertility preservation may be different from developed countries. The aim of the present study was to describe the reproductive status and clinical pathological features of young women diagnosed with BC in Latin America.METHODSLACOG 0414 is a prospective registry in Latin America which included young patients with &lt; 40 years old with diagnosis of BC and indication of (neo) adjuvant chemotherapy. Demographic data, reproductive status and clinical pathological information were retrieved from patients` medical charts. This study was approved by local ethics committees and regulatory authorities.RESULTSA total of 343 patients (pts) from 19 different sites distributed in 4 Latin American countries were included: Brasil (N=132 pts), Mexico (N=112 pts), Peru (N=83 pts) and Cuba (N=16 pts). The mean age at BC diagnosis was 34.02 (±4.17) years (14% had &lt; 30 years, 41% had 30-35 years and 44% had 36-40 years). From all included patients, 245 (71.42%) already had children at the time of BC diagnosis. From those the median number of children per women was 2 (range 1–6). The probability of having children at the time of diagnosis was significantly higher with increased age, being as high as 80% in those aged between 36 and 40 years old. There was no difference in terms of having a child at BC diagnosis within the 4 countries, by stage at diagnosis or per breast cancer subtypes.In terms of educational level, approximately 8% of patients were Illiterate and only 40% had university degree. Stages at BC diagnosis were the following: 12% stage I, 49% stage II, 35% stage III and 3% stage IV. The distribution of BC subtypes was: luminal 48%, HER2-positive 29% and triple negative 23%.CONCLUSIONTo our knowledge, this is the first study describing reproductive status of young patients diagnosed with BC in Latin America. Despite the lack of access to fertility preservation programs in the region, we found that a high number of patients had children at diagnosis of BC. Considering the high prevalence of advanced disease and aggressive subtypes the socioeconomic impact of young BC patients in Latin America needs to be addressed.Citation Format: Werutsky G, Villarreal-Garza C, Morante Cruz ZD, Debiasi M, Zaffaroni F, Fonseca A, Castro-Sánchez A, Platas A, Gómez Moreno H, Bretel D, Ortiz RM, Reinert T, Dybal V, Liedke P, Barrios C.
